Determination of cadmium, chromium, lead and nickel by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution has-digital Specific guides exist for electrical1 Scope This European Standard specifies a method for the determination of the content of cadmium, chromium, nickel and lead in fertilizers and liming materials using inductively coupled plasma atomic emission spectrometry (ICP AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg kg for Cd and 1 mg kg for Cr, Ni and Pb. NOTE 1 Due to
